To all whom it may concern:

Zen of the United States, residing in Quincy,

in the county of Adams and State of Illinois,

have invented certain new and useful Improvements in Pasteurizers, of which thefollowing isa full, clear','and exact description, referencebeing had to the accompanying drawings, "forming part of this speclfication.

My present invention relates to an appa- E ratus for pasteurizing. beer, one of the prin- I cipal objects of my invention being to simplify the constructio nand cheapen the cost of the apparatus,- as well as improving itsefficiency, by dispensing with a tank throughwhich the bottles of beer are carried to expose them-to the different temperatures-towit,in first attemperating' the beer, then heating it'to the.

i maximumtemperature, and finally cooling it 1 tion. Fig. II is a side elevation showing the auxiliary supply-tank in vertical section.

part in section. I Fig. IV is an enlarged detail Fig.1V is an enlarged long1-" tudinalsection showing one of the regulators.

Fig-VI isa detailv section taken on line VI VI, Fig. IV.

Referring'to the drawings, 1 represents a' 1 housing, that may be of any desired construe-- .tion and which is preferably located beneath the floor 2 of a building.

' indispensable; but I prefer to use it for the purpose of inclosing the working parts and protecting them from v1ew and alr-currents.

3 represents a pair of endless chains between which baskets or receptacles 4 are supported, preferably by means of stems 0r trunnions 5 projecting from the ends of the baskets, asshownin Fig. III. The baskets are adapted to receive the bottles of beer to be pasteurized, and they, with the chains, form the endless carrier of the apparatus. The chains pass over a pair of upper sprocket- This housing is not.

w wheels 6, behind a set of sprocket-wheels 7 7 Be it known that I, WILLIAM J. RUFF, a citiat one end of the machine, and behind a pair of sprocket-wheels 8 at the other end of the machine, the sprocket-wheels being secured to shafts suitably journaled in the housing 1' or other support.

3 represents guide-rails for di recti-ng the movement of the chains.

9 represents a main water-supply tank-that communicates with a drip-floor 10 through meansof a pipe 11, the floor beingv inclined upwardly in both directions fromthe center of the machine, as shown in Fig. I. The tank '9 is initially supplied with water through working there will be a circulation of water from the upper part of the tank through the pump and into the lower part of the tank.

17 represents a diaphragm-valve such as is shown in Fig. VII ofmy-IatentNo. 701,622,

dated June 3, 1902, in the pipe outwardly beyond the pump 14:. In order that this valve 17 may be automatically controlled to maintain a constant temperature of the water in .the tank 9, I provide the regulator shown in Fig. V. The regulator connects with the diaphragm of the valve 17 by means of a pipe 18. The regulator consists of a cylinder 19,

secured to the wall of the tank 9 and having VVitha tube 20,that extends into the tank. in the tube 20 is a thermostatic bar or rod 21, the inner end ofwhich is made fast to the end of the tube, as shown at 22,,Fig.-V. In the outer end of the cylinder 19 is fitted aplug 23,

into which is tapped a stem 24,having a port 9 25, that communicates with the pipe 18. The inner end of the stem 24 forms the seat for a valve 26 on the outer end of the thermostatic rod 21.

27 is a compressed-air pipe tapped into the plug 23 and which communicates with the interior of the cylinder 19. \Vhen the temperatnre in the tank 9 falls below a given pointsay 148 Fahrenheit the bar 21 will contract and open the valve 26. Compressed air will then pass through the pipe 27, (which is connected to a suitable compressed-air tank, not shown,) through the stem 2t,and through the pipe 18 to the diaphragm-valve 17, thus causing the valve to be opened and starting up the jet-pump by the passage of steam through the pipe 13. hen the temperature in the tank 9 is restored, the bar 21 will expand, closing the valve 26, thus stopping the action of the pump by shutting off the steam in the pipe 13. The stem 24 may be turned to adjust it inwardly or outwardly, so that 'the valve 26 will close sooner or later, thus enabling the operator to provide for the exact temperature desired in the tank 9.

I make no claim as inventor to the construction of the regulator which I have described, and any desired form of regulator may be used.

30 represents a pipe communicating with the supply-tank 9 and which extends to one of the upper corners of the machine, where it is provided with branches 31 and 32, that are located over the bottle-carrier, as shown in Fig. I. In the pipe 30 is a rotary pump 33 of any ordinary well-known construction, driven by a belt 34 from a pulley on a driving-shaft 35. When the machine is in operation, the pump 33 operates continuously and conducts water from the supply tank 9 through the branch 32, from which it flows into the passing baskets of the carrier. A

' portion of the Water passing through the pipe 30 escapes through the branch 31 of the pipe except when this branch is closed by an automatic diaphragm-valve 36, that corresponds in construction and operation to the valve 17. Water escaping through the branch 31 is deposited in the passing baskets of the carrier. It will be noted that the carrier moves in an upwardly direction toward the wheel 7 and as it leaves the Wheel moves in a downwardly direction. The branch 31 of the pipe 30 deposits water into the baskets on the advance side of the wheel 7, and the branch 32 deposits water into the baskets on the other or retreating side of the wheel 7. The stems or trunnions 5 of the baskets are made hollow, as shown in Fig. III, and they are connected together by means of flexible pipes 38 and loose sleeves 39, the sleeves fitting loosely on the trunnions, so as to be free to turn as the carrier passes around the sprocket-wheels. The pipes may either be made of flexible tubing, as shown at A, Fig. III, or may be made of plain telescoping sections, as shown at B, or maybe made of sections joined by a stufiing-box union, as shown at C. The trunnions of the baskets are connected together alternately at opposite ends of the baskets, as shown, so that water entering one end ofeach basket passes across the same and leaves at the other end, thereby producing a circulation of water through the baskets. As the water enters the baskets through the branch 31 of the pipe 30 it circulates through the baskets, passing from one to another until it reaches the lowest point, which is at D, Fig. l, and will here overflow into a catch-basin 4E0, from which it passes to the auxiliary tank tl through a pipe -12, and the water entering the baskets through the branch 32 circulates from one basket to the next until it reaches the lowest point in the underrunning part of the carrier, which is at E, Fig. I, and here the water overflows onto the inclined floor 10, from where it passes into the supply-tank 9 through the pipe 11. It will thus be seen that while the bottles are passing from the wheels 7 to the point 1*] there is a flow of water of the maximum temperature of 14:8 constantly circulated around them, and to prolong this period of exposure of the beer in the bottles to the maximum temperature I provide another pipe 413, that extends from the tank 9 to a. point at the rear of the wheels 8. This pipe is provided with a rotary pump 44L, driven from the shaft 35 by a belt 45. The pipe 43 deposits water into the baskets, and this water circulates from one basket to another to the point It, where it overflows and passes back into the tank 9.

Extending from the auxiliary tank 11 to a point near the supporting-wheel (5 of the carrier is a pipe &6, provided with a rotary pump 47, driven from the shaft 35 by a belt 43. This pipe deposits water from the tank 11 into the baskets as they descend from the supporting-wheel 6, and the water passes from one basket to another until it reaches the low point I) of the carrier, where it overflows into the catch-basin t0 and passes back into the tank 41 through the pipe 12. This water provides for the initial warming of the beer, and it is maintained at the desired temperature by means of water passing from the tank J into the baskets through the branch pipe 31, which, as stated, passes from one basket to another until it reaches the point I), where it overflows into the catch-basin and enters the tank L1. For automatically controlling the passage of water through the branch pipe 31 .1 provide the diaphragm-valve 36, which is connected by a pipe 49 to a regulator 50, located in the tank 41. The construction and operation of this regulator is the same as that shown in Fig. V, of which a description has been given. It Will thus be seen that the temperature of the water in the tank 4-1 is utilized to control the valve 36 and admit water from the maximum hot-water-suppl y tank 5) to regulate the heat of the attemperating or warming water in the tank 41.

For the purpose of cooling the bottles of beer while the carrier is passing from the wheels 8 to the wheels (5 v1 provide the pipe and 36.

46 with a branch 51,-that terminates at a point near the wheels 6 on the Opposite side of the wheels to the point where the attemperatingwater is discharged into the baskets, as seen in Fig. I. This water circulates from one.

basket to another and cools off the beer in the bottles. It overflows from the baskets at about the location of the wheels 8 as it is caused to back up by the'flow of water from pipe 43 into the baskets. The pipe 51 is provided with a diaphragm-valve 52-of the same construction and operation as the valves'18 With this diaphragm-valve connects a compressed-air pipe 58, provided with a valve 54, connected to a float 55, located in the tank 41. When the water rises in the tank 41 after the machine has been started in op eration, the float opensthe valve 54 and compressed air passes to .and opens the valve 52 in the pipe 51, thus permitting afiow ofwater through the latter pipe for cooling the beer. I It is apparent that when the use of the machine isto be temporarily stopped or stopped for the time being and it is desired toremove all of the bottles from the baskets there will be less water escaping from the baskets at the point E than when the machine is in full operation, this difference being equal to the amount of displacement caused by the introduction of fresh bottles into the baskets, which has now been stopped or discontinued owing to the fact that it is desired to empty the machine. This diminished flow of water into the tank 9 must be compensated for, for the reason that the use of cooling-water is required for some time after theinsertion of bottles into the baskets has been discontinued. To compensate for this diminished flow of water, I employ a pipe 56, connected with a water-main or other source of supply and which is provided with a valve 57 connected to'a float 58, located in the tank 9. When the machine is in full operation, this-float is held in its raised position-and keeps the valve 57 closed. When the flow of water from the baskets into the tank 9 is diminished .by no more bottles being placed in the baskets, the falling ofthe water in the tank 9 allows the float 58 to drop and open the valve 57 whereupon a flow of water passes through the pipe 56 into the tank 41, thereby keeping up a supply of water in tank 41 for cooling purposes. 60 represents an overflow -pipe through which water can pass from the tank 9 and prevent the overcharging of the tank in case this condition should be likely to arise.

It is desirable to have the baskets drained of water at the time that they reach the point wherethe bottles are taken fromthe baskets. To accomplish this, I provide each basket with g a hollowstem 61 (see Fig; VI) near its bottom,

upon which fits a sleeve 6, carrying a short pipe 62. Just before the baskets reach the wheels 6 these pipes come against astationary stop 63, (see Fig. I,) causing them to be turned inclined position, so that the water will drain from the baskets through the pipes and fall upon the inclined floor 10, from'where it passes back intothe tank 9 to be reused. As the baskets pass over the wheels 6 they are emptied and refilled with bottles, and as they are passing to a point beneath the pipe 46 the pipes 62 come against another stationary stop 64 and are moved from a downwardly to an upwardly inclined position, thus shutting off the escape of water from the baskets.

It will be seen from the foregoing that the bottles of beer are subjected to the'action of attemperating-water from the point where the pipe 46 discharges to the point D of low elevation and on up to the point where the carrier passes around the wheels 7, and from here on thebottles are subjected to the maximum temperature until they reach the back of wheels 8, and from thereonto the pipe 51 they are subjected to the action of thecoolingwater discharging from pipe 51. The bottles are removed from the baskets with the beer fully pasteurized at the side of the machine where the pipe 51 is located, and fresh bottles are'placed inthe baskets on the side of the wheels 6 where the pipe 46 is located.

By a machine thus constructed the beer is attemperated, pasteurized, and cooled down without the use of any tank and by the use of water circulating from basket to basket while the carrier is moving to bring the respective baskets from thereceiving to the discharge side of the wheels 6.
